The present invention is directed to an apparatus for minimizing power consumption in a cooling system. In one embodiment, the apparatus comprises one or more processors, one or more sensors associated with one or more regulated environments and one or more chillers that regulate temperature of the one or more regulated environments and a storage device, coupled to the one or more processors, storing instructions that when executed by the one or more processors performs a method. The method comprises gathering readings from the one or more sensors, determining a cost and power consumption associated with setting values for a plurality of control variables associated with the one or more chiller plants, selecting values for the control variables with a minimum cost as optimized control variable values and applying the optimized control variable values to the plurality of control variables to minimize power consumption of the cooling system.

Method and apparatus for optimizing control variables to minimize power consumption of cooling systems

A method of automatically controlling an extendable robot arm to avoid collisions while returning to a first position from a second position includes periodically storing locations of the robot arm as the robot arm moves along a forward path from the first position to the second position; applying heuristic algorithms to the stored locations to determine a return path to the first position, the return path including at least a portion of a retrace path retracing the stored locations of the forward path; and controlling the robot arm to return to the first position using the determined return path.
